Simon Pilgrim 30771e251f [X86][SSSE3] Lower vector CTLZ with PSHUFB lookups ...

This patch uses PSHUFB to lower vector CTLZ and avoid (slower) scalarizations.

The leading zero count of each 4-bit nibble of the vector is determined by using a PSHUFB lookup. Pairs of results are then repeatedly combined up to the original element width.
